PROCESS OF EXPLORING CRITERIA FOR OBSERVING CHILDHOOD PLAY TO SUPPORT EARLY CHILDHOOD TEACHERS

The purpose of this study is to investigate the process of exploring criteria for observing childhood play to support early childhood teachers. This study was conducted using a convergent design among mixed methods. ‘Literature research’ and ‘Delphi survey technique’ were used as methods of quantitative data collection, and ‘participation observation’ was used as a method of qualitative data collection. As a result of the study, observation criteria for a total of 21 questions in 3 areas were derived, including 7 questions on ‘play flow’, 7 questions on ‘play motivation’, and 7 questions on ‘peer play behavior’. This criteria for observing childhood play helps early childhood teachers to understand childhood play in depth from the children's perspective. In addition, it is expected that this standard can be used as a standard for observing childhood play with increased objectivity by reducing cases where each early childhood teacher who uses this standard interprets it differently due to subjective opinions. Furthermore, It is expected that this criterion will help early childhood teachers in kindergartens accurately understand childhood play and support childhood play

Cordycepin Suppresses Expression of Diabetes Regulating Genes by Inhibition of Lipopolysaccharide-induced Inflammation in Macrophages

Background: It has been recently noticed that type 2 dia-betes (T2D), one of the most common metabolic diseases, causes a chronic low-grade inflammation and activation of the innate immune system that are closely involved in the pathogenesis of T2D. Cordyceps militaris, a traditional me-dicinal mushroom, produces a component compound, cordy-cepin (3’-deoxyadenosine). Cordycepin has been known to have many pharmacological activities including immuno-logical stimulating, anti-cancer, and anti-infection activities. The molecular mechanisms of cordycepin in T2D are not clear. In the present study, we tested the role of cordycepin on the anti-diabetic effect and anti-inflammatory cascades in LPS-stimulated RAW 264.7 cells. Methods: We confirmed the levels of diabetes regulating genes mRNA and protein of cytokines through RT-PCR and western blot analysis and fol

A hybrid level-set method in two and three dimensions for modeling detonation and combustion problems in complex geometries

We present an accurate and fast wave tracking method that uses parametric representations of tracked fronts, combined with modifications of level-set methods that use narrow bands. Our strategy generages accurate computation of the front curvature and other geometric properties of the front. We introduce data structures that can store discrete representations of the location of the moving fronts and boundaries, as well as the corresponding level set fields, that are designed to reduce computation overhead and memory storage. ... Boundary conditions at wall and internal boundaries are implemented. We present examples from the resulting code to the applications of detonation shock dynamics and dendritic solidification.published or submitted for publicationis peer reviewe

Wave Tracking in Complex Geometries

138 p.Thesis (Ph.D.)--University of Illinois at Urbana-Champaign, 2003.A new equation of state (EOS) for a reactive, non-ideal explosive was developed to be used in the explosive applications. The new EOS was based on the earlier work of W. C. Davis, who developed equations of state for the reactants and products separately. The new EOS presents a plausible way to generate a tractable one that fits experimental data and that can be used for DSD theory. It can also be used as an input to the integrated software framework.U of I OnlyRestricted to the U of I community idenfinitely during batch ingest of legacy ETD

Multi-scale modeling of solid rocket motors: Time integration methods from computational aerodynamics applied to stable quasi-steady motor burning

Here we consider the problem of efficiently computing the stable burn-back of a solid rocket motor when the motor is in the quasi-steady burning regime of operation. When the motor is modeled as a cavity that is filled with a compressible fluid with normal mass and momentum and energy injection from the solid propellant surface, the problem posed is a standard one in steady computational aerodynamics.published or submitted for publicationis peer reviewe

Evaluating the Efficacy of Therapeutic Programs on Improving Cognitive Function and Depression among Older Adults Living with Dementia in Korea

The purpose of this study was to evaluate the effect size of programs for enhancing cognition and alleviating depression in older adults with dementia. This study selected 45 cognition and 37 depression programs, which conducted pre- and post-tests and had a treatment group and a control group comprising older adults living in Korea. This study conducted a meta-regression analysis to examine the moderating effect of the program location, number of sessions, intervals, group activities, and curriculum on cognition and depression. Most programs improved cognitive function and lowered depression symptoms. The heterogeneity of the effect size was large. The effect size of the number of sessions on a cognitive function significantly increased with an increasing number of sessions. The effect size of the group activity program on cognitive function was higher. The effect of healthcare institutions on depression was lower compared to other locations. To make more effective interventions for cognition and depression, long-term and group activity programs following a comprehensive curriculum will be required. The programs of healthcare institutions are encouraged to accept the advantages of other institutions and apply them to improve the effects of the programs on depression. Future studies shall focus on establishing concrete measures to enable healthcare institutions to connect older adults with dementia with various other institutions that offer long-term group programs

Effects of moving wavy bondary on channel flow instabilities

Instabilities of channel flow over a moving wavy boundary are investigated for an extensive range of values of the Reynolds number R below its critical value Re. The shear flow is bounded from above by a flat boundary and from below by a wavy boundary which moves at a constant speed in the streamwise direction. The basic flow consists of the original parabolic profile plus boundary wave, due to the wavy boundary, and in the presence or absence of Tollmien-Schlichting (TS) wave. Both systems for part of the basic flow due to the boundary wave and the TS wave and for three-dimensional infinitesimal disturbances superimposed on the basic flow are solved numerically by applying spectral collocation technique. Certain forms of the wavy boundary under certain speeds are found to be stabilizing, while some other types of the wavy boundary with certain speeds are found to be destabilizing. The shape and speed of the wavy boundary can affect significantly the parametric resonance, transition path and the spatial and temporal structure of the peak-valley type vortices which may evolve due to threedimensional instabilities of the basic flow
